The entity that would make ΔG to become negative at a given enthalpy and entropy is Changing the temperature (Option A)

Gibbs free energy

ΔG = ΔH – TΔS

Where

  • ΔG is the Gibbs free energy
  • ΔH is the enthalpy change
  • T is the temperature
  • ΔS is the change in entropy

NOTE

ΔG = +ve (non spontaneous)

ΔG = 0 (equilibrium)

ΔG = –ve (spontaneous)

From the Gibbs free energy equation, we can see that the entities that makes us the equation are

  • Enthalpy, ΔH
  • Entropy, ΔS
  • Temperature, T

Thus, we can conclude that the correct answer to the question is: changing the temperature (Option A) since the equation has nothing to do with neither concentration, pressure nor volume
